Summary

This study looked at whether taking probiotics alongside regular treatment could help lower blood sugar and improve lung function in people with both type 2 diabetes and chronic obstructive pulmonary disease (COPD). The trial planned to enroll 30 adults aged 50-85, but it was terminated early. Researchers measured changes in blood sugar levels and lung capacity over 12 weeks.
